This will be useful for the CPU job submission IOCTL, as the CPU job has the need to use information from the user extensions. Currently, the user extensions are parsed before the job allocation, making it impossible to fill the CPU job when parsing the user extensions. Therefore, decouple the job allocation from the job initiation.
